ing the knob 25. The plug may then be inverted and the knob 25 permitted to rest on any suitable surface, whereupon the liquid on the vanes 19 and 20 will drain into the. wick 22. This is then ignited, and in burning will heat the stem 17 and the spiral vanes 19 and 20. As soon as the asolcne is burned the pin is again inserted into the opening 13.

l hereafter when the combustible gases mixed with some liquid fuel are drawn through the carbureter and up through the passage 1, they will pass around the curved stem 17 and the spirals l9 and 20. and be whirled equal] onto the adjacent surfaces 29 of the mani old, regardless of the angular position of the plug 15 and spiral surfaces 19 and 20, when inserted into the opening 13. On account of the preheating ot' the stem. 17 and vanes 19 and 20, the fuel will be quickly vaporized thus enabling the engine to be easily started. The vaporization process is of course more rapid and thorough when the surfaces 2! against which the mixed gas and lidluid fuel is whirled, become heated.

he whirling motion given to the gases as they pass through the passage 1. around the curved portion 17 and the spirals l! and 2. equally divides the gases as they reach the branching of the passage into the horizontal manifold passage 4. This insures an even distribution of the gases to the trout and the rear cylinders.

As the engine continues to run the wall [2 between the intake and the exhaust manifold becomes heated from the exhaust gases passing through the passage h. This heats the "gases coming into the intake manifold and into contact with the wall [:3 and thus more completel vaporizcs them before entering the cylin ers.

person on leaving a machine \\'llll'll is er nipped with our device may conveniently lock the same by simply removing the plug 15 and slipping it into his pocket or otherwise carrying itv with him. No suction then of course can be produced in the intake manifold until the opening 13 is closed. This will be diflicult without an accurately titt ing plug, even. though a prospective thief may ave discovered the reason why the engine cannot be started.

Having thus described our invention, what we claim is:

1. The combination of an intake manifold with means for heating the same, a removable plug fitted into one of its walls, a projection on said plug, and a spiral vane carried by the pro'ection and extending to the walls of the inta e passage, whereby fluid passing therethrough may be heated.

2. In a device of the character described, the combination of an intake manifold havin an upright passage branching to a plura ity of cylinders, a plug in a wall opposite to said passage, a spiral vane carried by the combustible liquid plug and fitted against the walls of the upright passage am extending substantially to the point where said upright passage branches.

3. The combination with an intake manifold of a passage leading from the carburetor and flaring as it leads toward the cylindei: branches, a stationary helical vane extending substantially to the wall of the flaring pas sage and leading along that passage For a distance back from the point of bra ich iti g and adapted to give the gases a whirling mo. tion as they pass from said flaring passage to the branches.

4. The combination of an intake or exhaust manifold having an intermediate wall in common, the intake manifold having an upright passage taj'ieriug downwardly and having an opening opposite said passage, a plug occupying said opening, a projection carried by the plug extending downwardly into the passage spiral vanes carried by said projection and a wit-k between the plug and said vanes.

5. The combination with an intake manit'old having a passage leading from the carlam-tor and branching to a plurality of cylin dcrs. of a removable plug carrier by the manifold. and a fibrous substance carried by the plug and I blc liquid to be parts may be heated to linll.

8. The combination with an intake manifold of a removable plug tilted into one of its walls, a projection on said plug. spiral vanes carried by the projection and extending to the walls of the intake passage, a wick adjacent to said vanes adapted to carry whereby the vanes may be heated by removing the plug and igniting the combustible liquid while so removed.

9. The combination with an intake manifold and an exhaust manifold so arranged that exhaust gases heat the intake manifold,
